Plants needed water and some needed lots of light, yeah? Only the window panes in the greenhouse weren't exactly clean at the moment. This meant that getting the proper amount of light would be quite hard to do. Deciding this just wasn't right, Ella wandered over and assessed the situation. Some definite cleaning was in order.

"Don't worry, you guys. You'll have some light in no time at all." Captain Ella to the rescueeeee!

Then Ella pointed her wand at the window pane nearest her and said clearly, "Scourgify!" That's right, dirt. Time to be on your way.
